Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus capable of efficiently removing dust floating on a pool water surface.

[0002]

2. Description of the Related Art In a pool with an open water surface, such as a storage pool for storing underwater because it is a heating element or a dangerous substance, not only in the case of outdoor installation, but also in the case of indoor installation,
Dust generated during work around the pool and dust carried by the flow of ventilation air float on the surface of the pool.

[0003] Generally, pool water is purified by circulating through a purifier to maintain its cleanliness. However, impurities suspended or dissolved in the pool water are sent to the purifier together with the pool water to be removed. In addition, the dust floating on the pool water surface often stays and accumulates without being able to get on the flow of the pool water circulation.

[0004] Accumulation of floating dust on the pool water surface is not only aesthetically unfavorable, but also reduces the transparency of the pool water and hinders the visibility of underwater work in the pool. .

[0005]

As a method of collecting suspended matter on the surface of the pool water, a method of scooping with a cloth covered with cloth is often used. However, in the case of a large pool, not only the work efficiency is poor, but also a net is used. Since the length of the handle on which the device is attached becomes long and it takes a lot of labor to operate the device, a device capable of efficiently removing suspended matter is desired.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and is an efficient and simple method for removing floating substances on the pool water surface, which can automatically remove dust floating on a wide area of the pool water surface with a simple controller. It is to provide a device.

According to a second aspect of the present invention, the pool water inlet is formed on the upper side surface of the main body such that the center of its diameter is located substantially at the center of the pool water surface, and the pool water outlet is formed of the pool water. It is characterized by being immersed in water.

A third aspect of the present invention provides a box-shaped main body, an equipment room and a pump room provided in the main body, a submersible pump installed in the pump room, a filter installed in the equipment room, A hose connecting the inlet side and the discharge side of the submersible pump, and a jet nozzle connected to the outlet side of the filter via a branch hose and provided outside the equipment room are provided. The invention of claim 4 is
A pool water inlet portion is provided on the outer wall surface of the pump chamber obliquely for inflow of pool water.

Most of the floating dust on the water surface has a density higher than the density of the pool water, but floats due to the surface tension of the water surface because of its small weight. The suspended matter suspended in the pool water is sent together with the pool water to the pool water purifier, which is the original treatment device, and is collected. Therefore, extra work is required to collect the suspended matter. It is unnecessary and can be removed.

In addition, a water channel connecting the pool water surface and the pool water is provided, and a water flow driving device creates a water flow flowing from the pool water surface to the pool water along the water channel, so that floating substances on the water surface can be drawn into the water. did.

[0012] Further, by using the propulsive force of the device for freely traveling over a wide water surface and automatically removing suspended matter and the reaction force of the water flow generated by the water flow driving device as a steering mechanism, the device can be simplified. Can be achieved.
